Rails 4 ActionMailer Sending Email With Name not working as expected - ruby-on-rails-4

Question

I am having trouble testing my mailer. It appears assigning attributes [:to, :from, :reply_to] with a email in the format described as email-with-name doesn't work.
Here is a simple example.
class MessageMailer < ActionMailer::Base
def simple
mail(
from: "Aaron Test <aaron#test.com>",
to: "Aaron Test <aaron#test.com>",
reply_to: "Aaron Test <aaron#test.com>"
)
end
end
message_mailer_spec.rb
EXPECTED = "Aaron Test <aaron#test.com>"
describe MessageMailer do
before do
#email = MessageMailer.simple
end
it "expect `from` to eq #{EXPECTED}" do
expect( #email.from ).to eq(EXPECTED)
end
it "expect `to` to eq #{EXPECTED}" do
expect( #email.to ).to eq(EXPECTED)
end
it "expect `reply_to` to eq #{EXPECTED}" do
expect( #email.reply_to ).to eq(EXPECTED)
end
end
Test results all the same
1) MessageMailer expect `reply_to` to eq Aaron Test <aaron#test.com>
Failure/Error: expect( #email.reply_to ).to eq(EXPECTED)
expected: "Aaron Test <aaron#test.com>"
got: ["aaron#test.com"]
(compared using ==)
Anyone know how to assign [to:, from:, reply_to:] in the email-with-name format?
Am I missing something?
Are there different methods that hold the email headers that I can test against?

Answer 1

Ok I got it by testing against the header hash of the email.
This is how to test the values of 'from', 'reply_to' and 'to' in rspec.
describe MessageMailer do
before do
#email = MessageMailer.simple
end
it "expect `from` to be formatted correctly" do
expect( #email.header['From'].to_s ).to eq("Aaron Test <aaron#test.com>")
end
it "expect `reply_to` to be formatted correctly" do
expect( #email.header['Reply-To'].to_s ).to eq("Aaron Test <aaron#test.com>")
end
it "expect `to` to be formatted correctly" do
expect( #email.header['To'].to_s ).to eq("Aaron Test <aaron#test.com>")
end
end

* Update:
The square brackets you're getting indicate that you're receiving an array. So you need to extract the values out of the array to verify their validity. The reason for this is that you could have multiple addressees, so for example the object could return:
["Aaron Test ", "Renoir "]
As far as I understand, you don't need to use the square brackets, and you don't need to include the quote marks in the string.
These should work:
from: "Aaron Test <aaron#test.com>",
reply_to: "Aaron Test <aaron#test.com>"
